Answer:
Chromosome number in gametes- haploid (n)
Chromosome number in zygote- diploid (2n)
Explanation:
Sexually-reproducing organisms make use of gametes to reproduce. The gametes are produced via the process of meiosis, which is a cell division that results in daughter cells (gametes) that have their chromosomal number reduced by half. A diploid (2n) organism i.e. possess two set of chromosomes undergoes meiosis to produce haploid (n) gametes i.e. contains one set of chromosomes. The male parent produces haploid sperm while the female parent produces haploid egg.
During reproduction, these haploid gametes (sperm and egg) combine in a process called FERTILIZATION to produce a diploid ZYGOTE. The diploid zygote then divides and grows into the full organism. Hence, since a zygote is formed by the fusion of two haploid gametes (sperm and egg), it contains a diploid chromosome number i.e. sperm (n) + egg (n) = zygote (2n)
Answer:
Their culture
Explanation:
Culture is the total pattern of customs, ideas, beliefs, art, and technology of a particular group of people or society. It distinguishes the paths through life span of human beings despite having essentially the same biological constitution. It is the way of life of a particular group of people, that is socially transmitted from generation to generation
Because it is the control center for many hormones
MOST ENZYME ASSISTED REACTIONS ARE REVERSIBLE.
this is because :
1. most enzyme assisted reactions are fast , not slow.
2. most enzyme reactions cannot take place at any temperatures as enzymes get denatured at high temperatures and so are will become unable to work.
3. ribosomes are organelle in cytoplasm which form proteins for cells.....as enzymes are proteins we can say they also manufacture enzymes.......but it is not necessary that enzyme assisted reactions can only take place within a ribosome.
4. but it is known that MOST enzyme assisted reactions ARE reversible.
so option 4 is true.
